VOLUMETRIC FLUID-PRESSURE REGULATOR.

SPECIFICATION forming part of Letters Patent No. 415,204, dated November 19, 1889.

Application filed February 2'7, 1389. Serial No. 301,3 l8. (No model.)

To aZl whom it may concern.-

Be it known that I, WARREN D. HOUSE, a citizen of the United States, residingat Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Volumetric Fluid- Pressure Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invent-ion relates to certain new and useful improvements in volumetric fluidpressure regulators adapted to supply to the point of use within a given unit of tilne a uniform quantity of fluid whatever may be the variation of pressure in the supply-conduit.

In carrying out my invention I have de vised the construction illustrated in the ac companying drawings, wherein Figure 1 represents my invention in elevation as applied to the regulation of gas to a burner-tip. Fig. 2 represents a central ver tical section of the same; and Fig. 3 represents a plan view of the lower part of the regulator, the regulating-float being removed.

Similar numerals of reference indicate similar parts througl'iout the several views.

Referring to the drawings, the regulator proper consists of two parts 1 and 2, the former constituting what I shall call the shell and the latter whatI term the base, provided, respectively, with screw-threaded extensions 3 t for connection, the one with the burner-tip sleeve 5 and the other with the gassupply pipe. The upper part3 of the regulator is provided with an uptake or discharge-aperture 6, and around the lower portion of said uptake is an annular ridge 7, for purposes hereinafter to be described.

The part 1 of the regulator is turned out, as shown, so as to present an annular shoulder 8, and at its lower edge is provided with a screw-thread engaging with a similar screwthread upon the part 2, whereby the two parts may be moved from or toward each other.

The lower part 1 of the regulator is provided at its upper portion with a float-chamher 9, having a central hollow post 10, upon which the float slides. The float consists of a main body portion 11, fitting the definingwalls of thefloat-chamber, and a hollow sleeve 12, fitting the post 10, and has a cap or covl ering 16, preventing the exit of gas through the hollow post. At its bottom the floatchamber communicates by openings 13 with the gas-supply, and said gas-supply communicates by openings 14 with an annular space intervening between the exterior periphery of the main body portion of the part 2 and the interior surface of the part 1 below the shoulder 8.

The parts being constructed and arranged, as described, the operation of the invention is as follows: Assuming the two parts of the regulator to be screwed together, so that the shoulder 8 shall come in close contact with the shoulder 15, gas entering from the supply-conduit will enter the float-chamber 9 through the openings 13 and will enter a hollow post 10. The upward pressure thus produced upon the float will cause it to rise until the cap 16 strikes the ridge 7, closing the uptake 6. I then cause a separation of the shoulders 8 and 15 from each other by gradually unscrewing the part 1. Gas accordingly passes through the apertures it and annular space 17 between said shoulders into the regulatorchamber above the float, and exerting a counteracting pressure upon the upper surface of the float causes it to drop to a position corresponding to the pressure exerted by the amount of gas passing be tween the shoulders 8 and 15. It is evident that by increasing or diminishing the 0pening between the said shoulders 8 and 15 the float may be proportionately lowered, so as to admit a greater or less quantity of gas into the uptake 6. In this manner I am enabled to supply to said uptake exactly the quantity of gas required by the particular burner-tip in use for the production of aflame of the appropriate size and giving perfect combustion. Having secured this adjustment for a burn ertip adapted to consume four, five, six or any other number of feet of gas per hour, as the case may be, I may make this adj ustment coir stant by inserting between the parts a washer 18 and leading the screwthread connection. The regulator in this fixed adjustment of the parts 1 and 2 will supply in the same unit of time whatever may be the pressure in the gassupply pipe a uniform quantity of gas to the burner-tip, the float rising when the pressure in the gas-supply pipe increases, thereby lessening the inlet area to the uptake 6, and lowering when the pressure in the gas-supply pipe decreases, thereby increasing the inletopening to the uptake.

In this form of gas-regulator an increased delicacy is secured in the action of the float by reason of the fact that the guide-post 1.0 is hollow, thereby permitting the gas-pressure from below to act upon the central portion of the float instead of upon its main body portion only, while at the same time the total area exposed to pressure from below is proportionately increased. The cap 16 of the float being turned off smooth makes a tight joint, with the ridge 7 projecting downwardly from the uptake-opening 6, the sharp edges of said ridge cutting through any deposit that might form upon the cap 16. The small surface of contact between the annular ridge and the cap also prevents the cap from adhering to said ridge, which might otherwise happen should the cap be covered with a sticky deposit.

In an application of even date herewith, No. 301,347, filed by me I show a construction in many respects like that described herein; but this form of pressure-regulator (lifters from that in the other case, among other things, in the following respects: The float herein, instead of having an open-ended guidesleeve sliding upon a solid post, has a closed cap sliding upon and closing the upper end of a hollow post. Moreover, the float herein receives the pressurepf the gas not only on its main body portion, as in the other case, but on the central closed cap through the tubular post. The gas passes in this case directly from the supply-pipe to the annular chamber between the base and the shoulder instead of first into the floatchamber and thence to the annular chamber, as in the other case.

Having thus described my invention, what I claim is- 1. A fluid-regulator consisting of theshell l and base 2, relatively adjustable with respect to each other, the shell being provided with a central uptake 6 and an annular shoulder 8, and the base having at its top a floatchamber provided with a hollow central guide-post and bottom openings, both communicating with the gas-supply, an annular shoulder 15, and side openings '14:, leading from the gas-supply to an annular space between the base and the shell-wall below the said shoulders 8 and 15, and a float having a tubular cap closed at its upper end and sliding upon the guide-post, substantially as described.

2. A fluid-regulator consisting of the shell 1, having central uptake 6, an annular ridge '7 around its lower end, and an annular shoulder 8, and the base 2, having an annular shoulder 15, co-operating with the shoulder 8, the base also having in its upper portion a float-chamber 9 and a hollow guide-post 10, both communicating with the supply, and a float 11, having a closed tube covering the hollow post and guiding the float onthe post,- said supply communicating by openings 14 with an annular space below the shoulders 8 and 15, substantially as described.

3. A fluid-regulator consisting of the shell 1 and base 2, relatively adjustable with respect to each other, the shell being provided with a central uptake (5, having an annular rid e 7 around its lower end and an annular shoulder 8, and the base being provided at its-top with a float-chamber having a hollow central guide-post and bottom openings, both communicating with the gas-supply, an annular shoulder 15, and side openings 14,1eading from the gas-supply to an annular space between the base and the shell-wall below the said shoulders 8 and 15, and a float havin g a cap or closed tube sliding upon and closing the upper end of the hollow guidepost, substantially as described.

4:. A fluid-regulator provided with a floatchamber, a hollow central guide-post within said float-chamber, and a float governing the exit-opening to the point of use, said exitopening having a ridge projection, said float sliding upon said post and having a cap closing the hollow guide-post, said float-chamber communicating on opposite sides of the floatchamber with the gas-supply conduit, substantially as described.

5. A fluid-regulator provided with a floatchamber, a hollow central guide-post within said float-chamber, and a float governing the exit-opening to the point of use, said float sliding upon said post and having a cap closing the hollow guide-post, said float-chamber communicating on opposite sides of the float with the gas-supply conduit, substantially as described.

6. A fluid-regulator consisting of the base 2, having an external screw-thread, and the shell 1, having the mating internal thread, the shell also having the central uptake 6 and the annular shoulder 8, the base having a float-chamber in its top with a hollow central post, both post and chamber communicating 'with the supply, an annular shoulder outside of the chamber co-operating with the shoulder 8 on the shell, an annular space between the base and the shell-wall, a float filling the chamber and sliding and guided on the post by a central closed cap covering the mouth of the hollow post, and openings leading from the annular space directly to the supply, substantially as described.

In testimony whereof I affix mysignature in presence of two witnesses.
